IMPROVEMENT IN RAILROAD DUMPlNG-CARS.

Specification f r.ning part of Letters. Patent No. @2362, dated May 24, 1864.

To all whom it may concern g Be it known that I, THOMAS A. MCFAR- LAND, of Meadville, in the county of Oraw;

ford, in the State of ,Pennsylv'auia, have in: vented a new. and Improved Railroad Dump ing-Car; andI do hereby declare'that, the

following is afull and exact description of the same, reference being had to the acooin-i v s and the letters of reference marked'theiemu .2

Figural. representsa perspective drawing of my car, showing all the machinery (as as can be seen) in-working'orden' Fig 2 is a=,

top view of the frame orbed of my car withdirt-box removed,.better showing its construction.

A A, Fig 1, is the dirt-box. This is open on one side to better spill out the dirt when the same is desired. This box rests on a line of rollers,.3 45 6, Fig. 2, so that. when loaded itcan be freely moved to oneLside of the car.

H -H H H are the car wheels, and u the axle. On this axle are two drums, at and n, so constructed as to revolve on the axle u.

O is a clutch, which revolves with the axle u, and is or may be moved to the right or left by means of the levers F G, and thus brought in contact with either of the drums" on or-n, as desired, causing them tov-revpf'lve This clutch is-I'repre'sented in the drawings and model with projecting teeth to hit corresponding teeth in the drums m and n and yet itmay be constructed with out the teeth, so as tooperate with friction alone-probably the better construction.

Q is a rope passing under the drum n and a number of times around it, then around the pulley 2, and is attached to the under side of' the dirt-box A A at -a point, It. v

P is atsimilar rope passing over the drum m and aroundit several times, and then around the pulley 1, and is likewise attached to the un-. der side of the dirt-box A A atapoinhfit New, when the car is loaded and drawn to the spat where it is desired to dump it, by moving the; levers G F so as to throw the clutch O in contact-with the drum m, causing ittorevolve and wiadeaptherepethceby-drawingth dirt-box to'the right until.i tseenter of gravity is past the last-rollers, 6 and 4, vi hen it will. ,tip up and unloador dump the dirt. By re-= versin g the levers G F the clutch O is brought into contact with the drum n, (and at the same time releasing m,)-thereby ca'n'sing njlto re volve, winding np'th'erope Q, and thereby drawing the dirtbox A A back to its proper place. Suitable stops can be constructed to prevent the dirt-box' from moving farther than is desired, but as these v are obvious mechanical devices, they are not representedin the drawings, bnt will suggest themselves to t-hemind of any mechanic.

What I claiin'asmy invention, and desire to secure by Letters Patent. of the United States, is- 1 4 The movable dirt-box A A, the revolving :drun'i's m and n, the .levers Grand F the ropes P and Q, and pulleys -1 2, when the same are constructed as described, and in the aforesaid combination, for the purposes. set. forth.
